Exclusive Electro-Disintegration of 3He at High Q2
Year: 2004
Type: preprint
Abstract: We develop a theoretical framework for calculation of high $Q^2$ exclusive electro-disintegration of A=3 systems. The main result of this work is the calculation of the final state interaction of the struck energetic nucleon with recoil nucleons within the generalized eikonal approximation (GEA) which allows us to account for the finite and relatively large momenta of the bound nucleons in the nucleus. The important advantage of this approach is the possibility to study in a self-consistent way the short range correlations in nuclei. This is due to the fact that GEA does not require a stationary condition for recoil nucleons as conventional Glauber approximation does, treating explicitly the Fermi motion of recoil nucleons in the nucleus. Based on our calculations, within the decay function framework we study the two-nucleon emission reactions in high $Q^2$ electro-disintegration of $^3He$. Our main motivation here is to explore the accessibility of two-- and three--nucleon short range correlations in $^3$He as well as to isolate unambiguously single and double rescattering processes in the reaction dynamics. Our analysis allowed us also to identify new approaches for investigating the role of the practically unknown three-nucleon forces in the ground state wave function of $^3He$.
